VAPOR-LAMP.

Specification of Letters Patent No. 28,652, dated. June 12, 1860.

- scription of the construction and operation of the same, reference being had to the annexed drawings, makmg part of this specification.

The nature of my invention consists in constructing hydrocarbon vapor generators in such a manner that the tube which conveys the fluid upward to the generator and also the tube which conveys the vapor downward to the burner are both contained in one piece of metal as shown.

To construct my invention make the parts externally as shown at Figure 1 having the tube (B) connected by screw connection with a pipe leading to an elevated reservoir in any convenient position in the building where it is to be used. To pipe (B) connect the faucet or stop cock (C) having a packing box (D) around its stem. To the parts mentioned connect the double conductor (E) by screw connection at (F). The conductor (E) is made of brass or other suitable metal, and the larger tube is either drilled or east through it from end to end. The smaller tube (H) is made in like manner from the upper end to a point where it connects with the tube (I) of the burner (J At the upper end of the double tube connect the double chambered generator (K) so that the chamber (L) occupying one side of the generator shall be connected with the tube (H), and the chamber (0) occupying the other side of the generator shall connect with the other or larger conducting tube The two chambers in the generator are so connected together, that the fluid must pass from the tube (G) into the chamber 0) thence through the partition (P) at R) into the chamber (L), thence into the tube (H) and downward to the burner (J Into the conducting tube (G) place a piece of wire (S) which shall nearly fill the tube, and near two inches in length. Fill the lower part of the tube with cotton packing.

To use the invention turn on the fluid by the cock (C) in sufficient quantity to supply the flame. The flow will be made uniform by the cotton packing, and the great heat of the upper part of the double tube and the generator (K) will change the liquid in vapor and supply the burner for a continuous flame. Before turning on the liquid, the generator should be highly heated by a flame in any convenient manner well known.

By using the double tubes for conducting the liquid and vapor in one solid pieceas shown I find the upper part of the tube much hotter than when the tubes are separate, and the liquid more perfectly vaporized. I also find the solid packing in the upper part of the tube to work better than loose material heretofore in use, and the tube is more easily cleaned out after use. By forcing the liquid in a thin sheet in contact with the surface of the tube it is readily changed into vapor.

WVhat I claim as my invention and desire to secure by Letters Patent, is,

The construction of the conducting tubes (H) and (G) in one solid piece of metal (E) substantially in the manner and for the purpose stated.
